jak1/2/3 inhibitor 1

JAK1 2 3 Inhibitor 1 is a potent protein kinase inhibitor.JAK1 2 3 Inhibitor 1 has antitumor activity that inhibits the growth of a variety of cancer cell lines. It inhibits the growth of cancer cells by binding to the cancer cell backbone and inhibiting the production of new proteins.

Tofacitinib Citrate (CP-690550 citrate) is a a potent, cell-permeable inhibitor of JAK1 2 3 (IC50s: 1 20 112 nM).

HM43239 is an orally active and selective FLT3 inhibitor with IC 50 s of 1.1 nM, 1.8 nM and 1.0 nM for FLT3 WT, FLT3 internal tandem duplication (ITD) and FLT3 D835Y kinases, respectively. HM43239 directly inhibits the kinase activity of FLT3 as a reversible Type I inhibitor and effectively modulates downstream p-STAT5 and p-ERK. HM43239 also demonstrated inhibition of SYK, JAK1 2 and TAK1. HM43239 inhibits the proliferation and induces the apoptosis of leukemic cells [1] [2] [3].

Tofacitinib-d3 Citrate is a deuterated compound of Tofacitinib Citrate. Tofacitinib Citrate has a CAS number of 540737-29-9. Tofacitinib citrate is a a potent, cell-permeable inhibitor of JAK1 2 3 (IC50s: 1 20 112 nM).

DualCathepsinL JAK-IN-1 (Compound A8) serves as a dual inhibitor of Cathepsin L (CTSL) and JAK, exhibiting IC50 values of 0.68 μM for CTSL and 337.1 nM, 5.251 nM, 27.29 nM, and 172.6 nM for JAK1 2 3 and TYK2, respectively. This compound effectively prevents the activation of MAPK, NF-κB, and JAK STAT signaling pathways, leading to significant anti-inflammatory therapeutic effects. DualCathepsinL JAK-IN-1 is applicable in research on acute lung injury (ALI).

JAK2-IN-7, a selective inhibitor targeting Janus Kinase 2 (JAK2), exhibits inhibitory concentrations (IC50) of 3 nM for JAK2, 11.7 nM for SET-2 cells, and 41 nM for Ba F3 V617F cells, indicative of its potency and selectivity. This compound demonstrates more than 14-fold selectivity against JAK1, JAK3, and FLT3, underlining its specificity. JAK2-IN-7 effectively induces cell cycle arrest at the G0 G1 phase and promotes apoptosis in tumor cells, manifesting significant antitumor activities [1].

JAK-IN-1 shows improved selectivity for JAK3 over JAK1. JAK-IN-1 is a JAK1 2 3 inhibitor with IC50s of 0.26, 0.8 and 3.2 nM, respectively.

Tuspetinib (HM43239) hydrate is a selectively active FLT3 inhibitor for oral administration, demonstrating IC₅₀ values of 1.1 nM for FLT3 WT, 1.8 nM for FLT3 internal tandem duplication (ITD), and 1.0 nM for FLT3 D835Y kinases. As a reversible type I inhibitor, it suppresses FLT3 kinase activity and influences signaling pathways including p-STAT5, p-ERK, SYK, JAK1 2, and TAK1. Additionally, Tuspetinib hydrate inhibits leukemic cell proliferation and triggers apoptosis [1] [2] [3].
